Are they actually being sent from your computer or web mail (look in the sent box) or are they spoof emails which just appear to be from you? The latter is more likely. Change e-mail password. But if it continues you may have to change e-mail address.
As I said in my last posting,I changed my password and all seemed to be well ,but now I am getting this message. Mail seems to be coming in but no mail is getting sent can someone tell me how to fix this please. In words of one syllable please as I am out of my depth with this one. Thankyou.

You'll need to check your e-mail account settings and that the new password is being recognised for the send part. I'm way out of date with Outlook Express so hope someone else can point you in the right direction.
